 Secure boot and restricting USB ports are two components that can reduce the attack surface on an endpoint. The attack surface is the sum of all paths for data into and out of the environment. Reducing the attack surface means minimizing the number and complexity of these paths, and thus reducing the opportunities for attackers to exploit vulnerabilities or gain unauthorized access. Secure boot is a feature that ensures that only trusted and verified code can run during the boot process, preventing malware or unauthorized software from compromising the system. Restricting USB ports is a policy that limits the use of USB devices, such as flash drives or external hard drives, that can introduce malware or exfiltrate data from the endpoint.

Role-Based Access Control (RBAC) is an approach to restricting system access to authorized users based on their roles within an organization. It depends on the job functions that individual users have as part of their responsibilities and is designed to reduce administrative work by assigning roles based on job competency, authority, and responsibility. References: Cisco Cybersecurity Operations Fundamentals, Module 1: Security Concepts, Lesson 1.2: Data Protection, Topic 1.2.2: Access Control Models

Traffic tapping involves replicating network traffic and sending it to a separate port where it can be analyzed without affecting the original traffic flow. This allows security analysts to monitor and analyze traffic for potential threats without the risk of blocking legitimate traffic.

Deep packet inspection (DPI) analyzes the data part (and possibly also the header) of a packet as it passes an inspection point, searching for protocol non-compliance, viruses, spam, intrusions, or defined criteria to decide whether the packet may pass or if it needs to be routed to a different destination. Stateful inspection, on the other hand, tracks the state of active connections and determines which network packets to allow through the firewall. While stateful inspection tracks the state of connections (Layer 4 - transport layer), DPI goes further by examining the payload of the packet (Layer 7 - application layer).

 In Wireshark, to filter traffic for a specific LAN, the correct syntax uses ip.src== and ip.dst== to specify the source and destination IP addresses. The /16 denotes the subnet mask, indicating that we are interested in the entire 10.11.x.x range. This filter will show all traffic where both the source and destination IP addresses fall within the specified LAN, excluding any internet traffic. References: The information is based on the Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) course, which covers network intrusion analysis and the use of tools like Wireshark for traffic analysis1.

 According to the NIST Incident Handling Guide, the analysis phase is the next phase of this investigation. The analysis phase involves examining the evidence and determining the impact, scope, and cause of the incident. The analyst should also identify the attacker’s methods, tools, and objectives, as well as any indicators of compromise or malicious activity. The analysis phase may also involve collecting additional data, such as logs, network traffic, or malware samples, to support the investigation. The analysis phase is crucial for developing an effective response and recovery strategy, as well as preventing or mitigating future incidents. References:

HTTPS uses SSL/TLS encryption to secure data transmission over the internet. This encryption makes it difficult to monitor HTTPS traffic because the data packets are encrypted making them unreadable to anyone trying to intercept or monitor the data without proper decryption keys. References := Cisco CyberOps Associate

To search for additional downloads of a malicious file by other hosts, the file hash value is needed. The hash value provides a unique identifier for each specific file version, enabling cybersecurity professionals to track down identical files across networks. References := Cisco Certified CyberOps Associate Overview

The command “$ cuckoo submit --machine cuckoo1 /path/to/binary” indicates that a binary located at “/path/to/binary” is being submitted to be run on a virtual machine named “cuckoo1”. This is a common practice in cybersecurity to analyze the behavior of suspicious files in an isolated environment. References: Cisco Cybersecurity documents or resources are needed for more detailed information.
